Single-family house 180-190 sqm on a 10x20m building plot, first draft general contractor

For me, everything is in one font size

Builderbob, find out what number of parking spaces is required. Usually, there are regulations about how many and how. For example, with us, they are not allowed to be arranged one behind the other; each parking space must be individually accessible. But each municipality regulates this itself, including the number. However, it will probably not be possible to have fewer than two parking spaces for a single-family house.
The question is whether they have to be garages/carports or if plain parking spaces are also allowed. The latter require less space. A combination of garage/covered parking space or carport/open parking space would also be worth considering. Or a double carport with a wooden wall on the weather side. This also requires less space than a garage with walls around it (with those, you can only open the car door as far as the wall – with an open parking space/carport, you can open it beyond that).

I would also be surprised if parking spaces arranged one behind the other are counted as 2 spaces. Here in Bavaria, the type doesn't matter. The main thing is that they are not one behind the other.

Usually there are regulations about how many and how. For example, with us they are not allowed to be placed one behind the other, but each parking space must be individually accessible. However, each municipality regulates this differently, including the number. But it probably won't work with less than two parking spaces for a single-family house anyway.

I took a look at the municipality's parking space ordinance: "(1) Garages and parking spaces must be accessible without crossing other parking spaces. (2) If more than one parking space is required for an apartment, this additional parking space can also be arranged so that the other parking space belonging to this apartment is blocked in." The development plan states the following: "In general residential areas, only open and covered parking spaces with a maximum distance of 6.0 m from the street boundary line are allowed outside the buildable property area defined by building boundaries. Garages must maintain a minimum lateral distance of 1.50 m from traffic areas and public green spaces with their driveways." This means for me: for a single-family house (1 "apartment" in the sense of the ordinance) I can arrange two parking spaces one behind the other. The 6 m distance from the street boundary line for the parking space further away from the street should be sufficient for that. Since only open and covered parking spaces are allowed outside the building boundaries, garages are probably ruled out due to the narrow plot (unless I place them all the way at the north of the building envelope and the house behind it)... After giving it some more thought, a double carport wouldn't be bad at all. But I don't see where I could fit it, except directly at the street with the house behind it. Unlike garages, the carport should be allowed directly at the street and wouldn't have to be within the building envelope = maintain a 3 m distance?

Apartment and single-family house are usually not the same! Please check on that again.

So, I played around with a double carport (because the 1.5m rule only applies to garages) and an entrance in the northeast ...

However, I am still not satisfied with the upper floor plan. I have now placed the utility room as a laundry room on the upper floor because there was no space in the ground floor due to the carport corner. Unfortunately, this has made the upper floor somewhat compartmentalized. The children's rooms have also turned out rather large, but moving the stairs would reduce the size of the office again. Or I could give up the gimmick of a "covered outdoor area" in front of the office. But I really miss a small covered terrace area in our house – it doesn't have to be on the main terrace.

But actually, the main terrace facing southwest would be nicest, right? So better move the office back upstairs ... I already have a new idea again ...

"In general residential areas, only open and covered parking spaces with a maximum distance of 6.0 m from the street boundary line are permitted outside the building boundaries defining the buildable plot area.

Well, I read here that every parking space (outside the building boundaries) – whether open or covered – must have a minimum distance of 6 m from the street. But we can ask ...?
